Scientific Linux Security Update : qemu-kvm on SL7.x x86_64 (20150727)

A heap buffer overflow flaw was found in the way QEMU's IDE subsystem handled I/O buffer access while processing certain ATAPI commands. A privileged guest user in a guest with the CDROM drive enabled could potentially use this flaw to execute arbitrary code on the host with the privileges of the...

qemu/kvm: i8254: out-of-bounds memory access in pit_ioport_read function

An out-of-bounds memory access flaw, leading to memory corruption or possibly an information leak, was found in QEMU's pitioportread function. A privileged guest user in a QEMU guest, which had QEMU PIT emulation enabled, could potentially, in rare cases, use this flaw to execute arbitrary code o...

USN-2692-1 qemu vulnerabilities

Matt Tait discovered that QEMU incorrectly handled PIT emulation. In a non-default configuration, a malicious guest could use this issue to cause a denial of service, or possibly execute arbitrary code on the host as the user running the QEMU process. In the default installation, when QEMU is use...
